Zusatztext For the reader with some previous exposure o the subject, this book does a marvellous job of putting things in their place, and includes some clear explanations of some potentially difficult topics. This is a unique book with many valuable insights. Mathematical derivations are balanced by clear, qualitive descriptions of what is going on. It must be essential reading for anyone starting off in the study of water-rock interactions, as well as being an extremely valuable reference for people already wrestling with such problems.Journal of petrology Klappentext Geochemical reaction modeling plays an increasingly vital role in several areas of geoscience, from environmental geochemistry and petroleum geology to the study of geothermal and hydrothermal fluids. This book provides an up-to-date overview of the use of numerical methods to model reaction processes in the Earth's crust and on its surface. Early chapters develop the theoretical foundations of the field, derive a set of governing equations, and show how numerical methods can be used to solve these equations. Other chapters discuss the distribution of species in natural waters; methods for computing activity coefficients in dilute solutions and in brines; the complexation of ions into mineral surfaces; the kinetics of precipitation and dissolution reactions; and the fractionation of stable isotopes. Later chapters provide a large number of fully worked calculation examples and case studies demonstrating the modeling techniques that can be applied to scientific and practical problems. Students in a variety of specialties from low-temperature geochemistry to groundwater hydrology will benefit from the wealth of information and practical applications this book has to offer. Zusammenfassung This is the first text/reference to treat the field of geochemical reaction modelling in its entirety. The book will (1) develop the field's theoretical basis and governing edquations in a logical sequence, (2) give concrete examples of how the techniques may be applied, and (3) present case studies that build on sample problems.
